DEFENDER SAFETY SYSTEM® HIGH EF TTW® POWER VENTED MODELS

The High EF TTW® series offers additional insulation, resulting in higher Energy Factor ratings and qualifies for Energy Star® requirements. Like our TTW1® and TTW2® series, these models are power vented for positive exhaust. They offer greater installation flexibility with the ability to vent through a wall of roof, with either 2" or 3" PVC, CPVC or ABS.
